Choose Fly.io if you need cost efficiency, global distribution, Docker container flexibility, or run latency-sensitive applications—it's better for scaling and international users but requires more technical knowledge.","keyDifferences":[{"label":"Starting Monthly Cost","winner":"b","entityAValue":"$7 (basic dyno)","entityBValue":"$0 (free tier with 3 shared-cpu VMs)"},{"label":"Pricing Model","winner":"b","entityAValue":"Per-dyno + add-ons (~$50-500/month typical)","entityBValue":"Per-minute usage (~$0.0000228/CPU-hour)"},{"label":"Global Edge Network","winner":"b","entityAValue":"4 primary regions (US, EU, Asia)","entityBValue":"28+ regions worldwide with automatic deployment"},{"label":"Setup Complexity","winner":"a","entityAValue":"CLI-based, beginner-friendly (5-10 min deploy)","entityBValue":"CLI-based with Docker, requires more config (15-30 min)"},{"label":"Free Tier Credits","winner":"b","entityAValue":"$50/month (discontinued Nov 2022, then $7 minimum)","entityBValue":"$3/month always available, no credit card required"}],"winner":{"slug":"fly-io","name":"Fly.io"},"confidence":"high","entities":[{"name":"Heroku","slug":"heroku","url":"https://www.aversusb.net/entity/heroku","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/heroku"},{"name":"Fly.io","slug":"fly-io","url":"https://www.aversusb.net/entity/fly-io","alternativesUrl":"https://www.aversusb.net/api/v1/alternatives/fly-io"}],"faqs":[{"question":"Why is Fly.io so much cheaper than Heroku?","answer":"Fly.io uses a utility-based pricing model (pay-per-minute) and self-serve infrastructure without managed add-ons, while Heroku's dyno-based model includes managed services, support, and overhead. For a typical app, Heroku's $7 minimum + database ($9) + logging ($50) easily reaches $100+/month, whereas Fly.io's similar setup costs $15-25/month."},{"question":"Can I migrate from Heroku to Fly.io easily?","answer":"Migration requires some effort. You'll need to: (1) containerize your app in Docker, (2) export your Heroku PostgreSQL database, (3) recreate it on Fly.io, (4) update your app's configuration. Most simple apps take 1-3 hours; complex multi-app setups may take longer. Heroku's Procfile won't work directly—you need a Dockerfile."},{"question":"Is Heroku still worth using in 2026?","answer":"Yes, for specific use cases: rapid prototyping, non-technical founders, teams that value simplicity over cost, and apps with minimal scale. However, the 2022 free tier removal and price increases have pushed cost-conscious developers to Fly.io, Railway, and Render. Heroku remains strong for enterprises already locked into Salesforce ecosystems."}],"attribution":{"source":"A Versus B","url":"https://www.aversusb.net/compare/heroku-vs-fly-io)","license":"CC BY 4.0","citationFormat":"According to A Versus B (https://www.aversusb.net/compare/heroku-vs-fly-io)), Heroku is a mature, user-friendly PaaS with higher pricing ($7-50+/month per dyno) but simpler deployment, while Fly.io offers 3x lower costs ($0.0000228/CPU-hour) and better performance for globally ","dateModified":"2026-07-08T05:54:45.623Z"},"relatedQuestionsUrl":"https://www.aversusb.net/api/faq/heroku-vs-fly-io)","relatedComparisonsUrl":"https://www.aversusb.net/api/v1/related/heroku-vs-fly-io)","knowledgeGraphUrl":"https://www.aversusb.net/api/knowledge-graph/heroku-vs-fly-io)","claimReviewSchema":{"@context":"https://schema.org","@type":"ClaimReview","@id":"https://www.aversusb.net/compare/heroku-vs-fly-io)#claimreview","url":"https://www.aversusb.net/compare/heroku-vs-fly-io)","inLanguage":"en-US","isAccessibleForFree":true,"conditionsOfAccess":"Free","claimReviewed":"Heroku vs Fly.io","reviewBody":"Heroku is a mature, user-friendly PaaS with higher pricing ($7-50+/month per dyno) but simpler deployment, while Fly.io offers 3x lower costs ($0.0000228/CPU-hour) and better performance for globally distributed apps with more technical overhead.","datePublished":"2026-07-08T05:54:44.892Z","dateModified":"2026-07-08T05:54:45.623Z","reviewRating":{"@type":"Rating","ratingValue":5,"worstRating":1,"bestRating":5,"alternateName":"High Confidence"},"author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B","url":"https://www.aversusb.net"},"itemReviewed":{"@type":"WebPage","@id":"https://www.aversusb.net/compare/heroku-vs-fly-io)","url":"https://www.aversusb.net/compare/heroku-vs-fly-io)","name":"Heroku vs Fly.io","inLanguage":"en-US"}}}
